ATTACHMENT FOR AUTOMOBILE-WHEELS.

Specification of Letters Patent.

Patented Sept. i7, i912.

Application filed January 2, 1912. Serial No. 668,870.

Be it known that I, Flinn V. Gnovnn, a citizen of the United States, residing at Parli Rapids, 'in the county of Hubbard and State of Minnesota, have invented certain new and useful Improvements in Attachments for Automobi-le-VVheels, of which the following is al specification, reference being had to the accompanying drawings.

This invention relates to automobiles and more particularly to attachments for the wheels ci the same, that will enable the auto mobile to readily travel over slippery surfaces, such as ice and the like.

'lhe main object of this invention is to provide an attachment which V may be readily applied to an automobile wheel, so that the same may lbe enabled to readily travel over ice and snow.

Another object of this invention is to have the attachment so that it can be readily placed on or removed from an automobile wheel A.' still further object of this invention is to have the device as simple Aas possible so that it can be manufactured ata comparatively low cost, and so that the parts of the same can be readily inspected and repaired,

' wlieneverthe same is desirable. 30

Other objects of this invention will become apparent as it is more fully set forth.

In the construction shown by way of eX- ample in the drawings, Figure 1 represents a view in elevation of an attachment embod`ying this invention. Fig. 2 is a sectional View along the line 2-2 of Fig. 1. Fig. 3 is a detail of a chain used in this invention.

Similar reference characters refe-r to similar parts throughout the drawings.

In Jthe construction shown 'in the drawings, l represents an automobile wheel, which is :mounted on the attachment, which embodies this invention. The attachment consists in general of a frame portion 2, whose upper portion 3 is provided with means for engaging with the axle of the automobile Wheel, and whose lower portion has a pair of runners 4 attached thereto and arranged to come adjacent to the ground, or

to slide on the same as the case may-be.l

The frame has four sprocket wheels 5 ar- -the ground and thereby pended claim.

. posed pairs,

ranged to come in front oit' and in the rear of the automobile wheel, as is `clearlyshown in the drawings. A chain 6 is disposed on' the wheel and arranged to come in front of the automobile wheel, and to engage with the sprocket wheels 5, and also with a transversely bored sprocket casing 7, which is removably mounted on for the purpose of providing suitable meansv for transmitting the motion from the automobile wheel to the gears.

Mounted on the ehainare a number of cleats 8, which are arranged to engage with propel the vehicle. The slots 9 in the chain. are arranged to permit the sprocket teeth oi' thevcasing and of the wheels 5 to project therethrough, but not suihciently to extend beyond lthe cleats 8 The wheels are so disposed on the frameA as to project slightly beyond the runners so an automobile wheel,

that the'chain with its cleats will normally make engagement with the 'ice or ground over which the automobile runs. However, when running over snow, or, soft ground, the chaiirwill sink sufficiently into the same, to permit the runners to rest and slide on the. same. l

It can be readily seen that the automobile wheels will readily turn the sprocket Wheels, and also the chain in its mot-ion, so that no further description of the operation of the attachment appears necessary.,

Obviously while there is shown but one form of this invent-ion in the drawings, .it is not desired to limit this application for Letters Patent to that particular form, or in any other way otherwise than necessitated by 'the priorr art, as many modifications in the construction thereof may be "Without departing from.y the scope ot th'dtap- Having thus described this invention, what is claimed is :f-
